ac1b9b11dc Fixed deopt reasons in TaggedToI. 
Every DeoptimizeIf should be preceded by a RecordComment explaining
the reason. In the long run, the reason should be an argument of
DeoptimizeIf, but we're not there yet.

On x87, things are a bit ugly due to some pushing/popping, so if
somebody feels inclined to improve this: Feel free. Probably the right
approach would be reloading instead of the push/pop horror.

Another thing is our inconsistent handling of the "done" continuation
of deferred code on the various platforms, I made tiny changes on the
way, but this should better be unified somehow, with all those
micro-optimizations removed.

ac6074707a X87: Removing ic.h from code-stubs.h 
port r23977.

original commit message:

  Removing ic.h from code-stubs.h

  CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

  More work could/should be done here, but this is a first step.

069a9c75ad Move configuration of ResourceConstraints to Isolate construction 
We can only set resource constraints before the isolate is initialized.
Since in the future, we want to initialize isolates at construction
time, we need to set constraints there.

It's possible to later modify the stack limit, so introduce an
Isolate::SetStackLimit method for that.

The SetResourceConstraints method will be deprecated. Users should pass
ResourceConstraints to Isolate::New, and use Isolate::SetStackLimit to
later modify the stack limit.

65a1857824 Currently, a new isolate is created in an uninitialized state, and 
several API methods will automatically initialize it. During this
uninitialized state, code event handlers and function entry handlers can
be attached to the isolate.

This CL deprecates SetFunctionEntryHook and moves the configuration of
those handlers to the Isolate factory method.

This will allow for initializing the Isolate at creation time in the
future.

Users of V8::SetFunctionEntryHook should pass the entry hook to
Isolate::New instead. V8::SetJitCodeEventHandler should either be passed
to Isolate::New as well, or (if startup events are not required) invoked
via the Isolate.

00e90b7e6e Remove deoptimization by patching the call stack. 
We go back to patching the code for lazy deoptimization because ICs need the on-stack return address to read/update the IC address/state.

The change also fixes bunch of tests, mostly by adding more deoptimization points.

(We still need to add code to ensure lazy deopt patching does not overwrite ICs and other lazy deopts; this is coming next.)

original commit message:

  Added CallInterfaceDescriptors to all code stubs. A handful
  of code stubs are too complex to be described this way, and
  they are encoded with the macro
  DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().

  Along the way:
  * allowed inheritance of CallInterfaceDescriptors.
  * Defined static Register methods for some of the new
    CallInterfaceDescriptors. We could go a lot further here, but
    it doesn't have to be done immediately.
  * Added Representation arrays to some CallInterfaceDescriptors,
    especially where future hydrogen versions of the stubs could
    benefit from this knowledge.

4a5001ddd1 MIPS: Added CallInterfaceDescriptors to all code stubs. 
Port r23854 (3870059)

Original commit message:
Added CallInterfaceDescriptors to all code stubs. A handful
of code stubs are too complex to be described this way, and
they are encoded with the macro
DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().

Along the way:
* allowed inheritance of CallInterfaceDescriptors.
* Defined static Register methods for some of the new
  CallInterfaceDescriptors. We could go a lot further here, but
  it doesn't have to be done immediately.
* Added Representation arrays to some CallInterfaceDescriptors,
  especially where future hydrogen versions of the stubs could
  benefit from this knowledge.

02213097cf Improve x32 detection macro. 
When targeting the Microsoft ABI in 64bit mode, clang defines __x86_64__ but
doesn't define __LP64__ (Microsoft uses LLP64), so it would fall down the x32
path. cl.exe doesn't define __x86_64__ in the first place, so it didn't have
this problem.

Rather than trying to guess pointer size by looking at __x86_64__ and __LP64__,
check for pointer size directly using __POINTER_SIZE__. This is defined by both
gcc and clang, and eliminiates this problem.

This should fix hundreds of "error(clang): unknown type name 'Atomic64'" when
compiling v8 on Windows with clang for 64 bit.

a57c7ab69c Fix perf jitdump integration. 
When emitting JIT_CODE_LOAD for Crankshafted code exclude Safepoint Table from the size of the code.

This cleans up perf annotate output - because otherwise it confusingly tries to disassemble safepoint table.

3dbb3c39d5 Reland r23732: ARM64: Fix and improve --trace-sim register trace. 
- Use standard names (except that our GREY is the standard BLACK).
- Make non-bold colours explicit, otherwise the boldness can carry over
  into subsequent colour declarations.
- I've moved some colours around to make them consistent. Register value
  updates (which are very common) now stand out less than they did,
  making the less-common (and arguably more important) debug
  announcements appear brighter.
  - FP registers and values are now magenta.
  - Integer registers and values are now cyan.
  - Memory accesses are now blue.
- LOG_WRITE prints the source register for stores.
- Loads are logged with a format similar to that used for stores.
  Specifically, the memory address is printed alongside the new register
  value.
- Updates to D registers print the raw bits as well as the double value.
  Updates to S registers print the raw bits as well as the float value.
  (Previously, we printed both double and float interpretations of the
  bits, which was a bit cluttered.)

d0054c755f ARM64: Fix and improve --trace-sim register trace. 
- Use standard names (except that our GREY is the standard BLACK).
- Make non-bold colours explicit, otherwise the boldness can carry over
  into subsequent colour declarations.
- I've moved some colours around to make them consistent. Register value
  updates (which are very common) now stand out less than they did,
  making the less-common (and arguably more important) debug
  announcements appear brighter.
  - FP registers and values are now magenta.
  - Integer registers and values are now cyan.
  - Memory accesses are now blue.
- LOG_WRITE prints the source register for stores.
- Loads are logged with a format similar to that used for stores.
  Specifically, the memory address is printed alongside the new register
  value.
- Updates to D registers print the raw bits as well as the double value.
  Updates to S registers print the raw bits as well as the float value.
  (Previously, we printed both double and float interpretations of the
  bits, which was a bit cluttered.)
